Green #3

Green #3, also known as Fast Green FCF, is a synthetic food dye. It is a chemical compound created through laboratory synthesis, not derived from natural sources. Its primary purpose is to impart a green color to various food products.

Manufacturers add Green #3 to foods and beverages to achieve a green hue. It is often found in products like ice cream, frozen yogurt, cakes, cupcakes, snack cakes, cookies, and fruit bars, as well as some pancake and waffle mixes.

Green #3 is an FDA-approved color additive for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Green #3. JECFA has evaluated Green #3 and set an acceptable daily intake. EFSA has also evaluated this color additive. Some research has explored a possible link between synthetic food dyes, including Green #3, and hyperactivity in some children, but the evidence is mixed and not conclusive for the general population.
